Interlocking cubes
Update: I had another go at finding that original photo, and I think it was the one that appears with Richard Gain's ducted fan for Mendel90: https://pinshape.com/items/4488-3d-printed-low-profile-ducted-fan-for-mendel90-with-e3dv4-hot-end
I saw this design in a random photo (which of course I can't find again), but couldn't find an stl for it. It looked like an interesting thing to print so I created a model in OnShape:

I found it quite difficult to print, the overhangs are about 35 degrees and they have a tendency to curl, and the bed contact area isn't very big. But it did eventually work without supports, although it's not the cleanest print I've made.

Notes:
Rafts and support might help. I managed a print without either, but it was close to failure at times.
